SPECIFICATION forming part of Letters Patent N 0. 638,217, datedDecember 5, 1899.

Application filed August 16, 1899. Serial No. 727,410. (No model.)

To all whont it may concern.-

Be it known that we, GEORGE G. OROUSE and JOHN J. FOLEY, citizens of theUnited States of America, residing at West Union, in the county ofDoddridge and State of West Virginia, have invented certain new anduseful Improvements in Gas-Regulators and Autornatic Shut-Offs, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention relates to certain new and useful improvements ingas-pressure regulators, and has for its object the provision of novelmeans whereby any desired gas-pressure may be obtained.

The invention has for its further object to construct a device of theabove-referred-to class, wherein the gas-supply is automatically cut offin case an excess pressure in the main supply-pipe takes place.

The invention, briefly described, consists of a gate that will regulatethe gas-inlet and a balance check-valve that will regulate the outlet orsupply pipe, the said gate and balance-valve being regulated by means ofa collapsible bag and other mechanism that will be hereinafterdescribed.

The invention finally consists in the novel construction, combination,and arrangement of parts, to be hereinafter more fully described, andspecifically pointed outin the claims.

In describing the invention in detail reference is had to theaccompanying drawings,

forming a part of this specification, wherein like numerals of referenceindicate corresponding parts throughout the several views, and in whichFigure 1 is a side elevation of our improved gas-pressure regulator andautomatic shutoff. Fig. 2 is a vertical sectional view of the same. Fig.3 is a top plan view of the same. Fig. 4 is a vertical sectional View ofthe gaschamber carrying the balance check-valve. Fig. 5 is a verticalsectional View of the gasregulating valve leading to the collapsiblebag.

Fig.13 isa perspective view of the gas-chamber with the front plate removed.Fig. 14 is a perspective view of the front plate of the gas-chamber.

Referring to the drawings by referencenumerals, 1 indicates thegas-inlet leading from the main feed-pipe, and the referencenumeral 2indicates the outlet or supply pipe. The said inlet-pipe 1 is coupled toa casing 3, said casing having formed therein an opening 4:,said openingextending npwardlyand adapted to receive the gate 5, said gate operatingin said opening and regulating the inlet or supply of gas from thefeed-pipe. A bushing 6 is formed integral with said casing, said bushinghaving formed therein a screw-threaded opening 7, which is adapted toreceive ascrewthreaded plug 8. A rod 9 is adapted to operate through thesaid plug, bushing, and casing and being secured at its lower end tosaid gate 5 and having its upper end bifurcated, as shown at 10,.toreceive a balancelever 11, said balance-lever being fulcrumed at 12 to abearing 13, formed integral with the upper end 14 of the bulb. The lowerend of the said bulb carries an annular flange 15, said flange beingapertured and adapted to receive bolts 16, passing through the aperturedannular flange l7 and the lower section of the bulbl8. Atthelowerextremity of the bulb 18 and formed integral therewith is formedan annular flange 19, said flange being likewise apertured to receivebolts 20, serving as fastening means and extending through .a similarapertured flange 21, formed in the casing 22, containing thegas-regulating valve 23, to the collapsible bag 24, arranged in thesections of the bulb 14: and 18. The lower extremity of the said casing22 is coupled to a fitting 25, connecting with a pipe 26, forming aconnection between said fitting 25 and the casing 3. To the other end ofsaid fitting 25 is arranged a pipe 27, connecting to the gaschamber 28,having arranged therein the balance check-valve 29. The said gas-chamber28 carries a bearing 30, in which is pivotally secured an arm 31, uponwhich is ar ranged an upwardly-extendingrod 32, a sleeve 33 fitting overand surrounding said rod 32. The upper extremity of said sleeve 33 isbifurcated, as at 34, for the reception of the end of thebalance-lever11, the latter being pivotally secured thereto. The said balance-lever11 is further provided with a weight 35, which is slidably securedthereon, and said balance-lever is still further provided with a scale36, which is pivoted to said lever at 37 and extends through a yoke 38,arranged to the exterior-of the lowersection of the bulb 18.

The reference-numeral 39 indicates a disk arranged upon the collapsiblegas-bag, said disk carrying a stem 40, which is adapted to operatethrough the boss 41, arranged and formed integral with the upper section14 of the bulb. At the upper extremity of the said rod is secured abifurcated bearing 42, adapted to receive the said lever 11, which ispivotally secured thereto, as at 43.

A removable plate 44, having formed therein apertures 45, is secured tothe gas-chamber 28, which also has arranged therein apertures 46 for thereception of fastening means. A collar 47 is rigidly secured to theplate 44, through which extends a shaft 48, which is secured to thebalance check-valve 29. At the outer end of the said shaft are attacheda trip-arm 49 and a lever-arm 50, said lever-arm being provided at itsfree end with a weight 51. A guide 52 is also arranged upon thegas-chamber 28, said guide regulating the movement of the arm 31.

Upon the front of the casing 22 is secured a dial 53. A regulating-screw54, passing through said dial and forming valve 23, carries an indicator55, which is rigidly secured to the forward end of the said screw.

The operation of the device is as follows: Assuming that all parts arein proper position, and for the purpose of more clearly illustrating ourinvention, we will first describe the operation of our'automaticgas-regulator and shut-oft in case there is an excess pressure from themain pipe or supply. To obtain the requisite number of ounces ofpressure of gas, the screw 54 is turned, carrying with it the indicator,and opening the valve sufficiently to allow the collapsible bag toexpand to such a degree that will carry the disk 39 to such a point thatwill regulate the inlet governed by the gate for a certain amount of gasto enter the regulator to produce the desired pressure, the balancecheck-valve 29 being retained open by the pressure that will be broughtto bear against the same, and allowing the gas to travel through thepipe 2 into the supplypipe of the dwelling, as the case may be. In casethere is an excess pressure the collapsible bag 24 will further expandand will carry upwardly with it the disk 39, to which is attachedthe'rod 40, thereby tilting the balancelever 11 downwardly and closingthe inletport, by means of the gate 5, to a sufficient degree tocompensate for the excess pressure. Thus the pressure will be accuratelyand automatically regulated. W'e will now assume that the pressure inthe main pipe temporarily ceases. In this case the bag 24 will collapse,allowing the downward movement of the rod 40 and The end of the latterwill then engage the arm 32, forcing the trip-arm 31 downwardly andsimultaneously operating the lever 50, which will by gravity operate andclose the balance check-valve 29. When the pressureis again restored inthe main pipe, in order to again obtain a supply of gas it will berequired to tilt the lever 50 to its normal position.

To have shown in dotted lines of Fig. 1 of the drawings the operation ofthe device, and in view of the above description afurther explanation asto the operation is deemed unnecessary.

Particular attention is directed to the fact that our improvedgas-pressure regulator and automatic shut-off will automatically closeand shut off the supply of gas both in cases where there is an excesspressure and where there is a low pressure, and therefore provides asafeguard in regulators of this class against any marked variations thatmay take place in the main pipes. The many advantages thus obtained willbe readily apparent, as explosions and confiagrations are caused eitherby one or the other of the extremesnamely, a sudden high pressure or atemporary lack of pressure.

It will be particularly noted that various changes may be made in thedetails of construction of our improved device without departing fromthe general spirit of our invention.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is
